Sea-Dog Bilge Pump Switch Panel, On-Off-Auto with Breaker, Black, Part 423040-1

The Sea-Dog 423040-1 is an On-Off-Auto bilge pump switch panel that lets you control your boat's bilge pump directly from a single panel, without needing a separate bilge pump switch. The control switch selects between the automatic and manual (momentary on) function of the pump, and the panel includes a built-in breaker for circuit protection. Finished in black, it is designed as a clean, dedicated helm or panel-mounted control point for bilge pump operation.

This switch panel is part of the Sea-Dog line of bilge pump switch panels (423030, 423040, and 423046), which are commonly paired with a Sea-Dog Bilge Water Alarm Panel to provide both manual pump control and an audible/visual warning when bilge water rises above the float switch level. The 423040-1 is sold and tracked under Sea-Dog's own part number and UPC, making it easy to identify a genuine replacement or new installation.
